how to enlarge plastic hose end to go over larger cooper pipe? tried heat on hose!?

Question

hooking up small ice machine. copper pipe about same radius as outside dimension of plastic tube!

Answer 1

use a cone and insert into tube. gradually work on the tube. now insert into the copper pipe.

Answer 2

Depending on the type hose you're using, you might try heating the hose by placing the end of it in a container of HOT water for 5 or 10 minutes, then as quickly as possible slip it onto the tubing. Be sure to use a hose clamp. If this contraption is going to be inside a house where a water leak can cost you a lot of money to repair damages, it's better to spend the money to pipe it properly.

Answer 3

I don't think you could enlarge the plastic hose to fit over the tube. You would be better off going to plumbing supply store and asking for an adaptor fitting that would join the two together. That is very common and is the only way to make a leak-tight connection.

Answer 4

the plastic tube would have to be a bit larger than the pipe and then tighten the hose onto the pipe with a hose clamp.

Answer 5

try cooling the end of the copper pipe with ice, then
slip on the plastic hose.

Answer 6

outside dimensions are the same - buy a connector pipe- put both pipes in and either cement together or clamp - I would suggest that you buy a cement type of connector for the plastic side and cement together- then clamp the copper pipe - there are converstion kits out there in any hardware store--

Answer 7

You will need a compression fitting to reliably hook up between the 2 tubes. I included a link to an example. This is the best way to do it if you don't want a leak.

Answer 8

Don't screw it up and rig it up with heat.
Do it the right way.
Take the time to do it right, or don't do it at all.
Later on, it will leak and you will have a bigger mess to deal with.
Pay what it takes to get the proper fitting and hoses.
Somebody at the hardware store can probably help you do the right thing.

P.S. My dad did that to our sprinkler system, then covered it with concrete. Years later, it ended up leaking and I had to break up the concrete with a sledgehammer to get to the leak.

So, save a few cents and time by doing it the wrong way, but that is why professional plumbers get paid so much. They do it the right way.

Answer 9

Find a tapered object that fits in the tube...heat tube & fit over taper..remove when cool...should retain its size so you can slip it over the copper & then clamp with a hose clamp..

Answer 10

If it is a low temp thermoplastic, like PVC, polyethylene..., dip it in boiling water.

If it is a mid or high temp one, ABS, PEP, nylon,..., blow heat on it from a distance.

If it takes extreme heat, such as silicone, use an alcohol as a lubricant, the longer the carbon chain the better, propanol is better than ethanol which is better than methanol.
